Yes it’s in the AC position.

Last time mine wasn't working there was a small rock blocking the little tubes that let it condensate, worth a look if everything checks out I have a 2021 259D3

Found the issue once we started to pull vacuum. Condenser line at the door hinge had a break in it. Picking up a new line Wednesday, pull vacuum for 30 minutes and if all is well recharge and see how she goes.

Thank you all for the assistance.
